AIR-PURIFYING DEVICE FOR CREAMERY-VATS.

Specification of Letters Patent.

Patented June 3, 1913.

application led January 6, 1910. Serial No. 536,706.

To all whom 25 may concern:

Be it known that I, FRANK R. NooNAN, of Alexandria, Douglas county, Minnesota, have invented certain new and useful Improvements in Air-Purifying Devices for Creamery-Vats, of which the following is a specification,

My 'invention relates to devices for cooling or aerating cream or milk and the object of the invention is t0 prov-ide an air purifying means through which the air is passed before delivery to the cream or milk vat.

My invention consists generally in interposing a tank containing a purifying agent, such as lime, betweenthe Ivat and the air pumps.

In the accompanying drawings forming part of this specification, the figure is a sectional View illustrating the application of my invention to a cream or milk'vat. y

In the drawing, 2 represents a vat adapted to contain cream or milk and having the usual coil 3 driven from a vSuitable means, not shown, and connected with the water and steam pipes 4 and 5, in any preferred manner.

6 is an air pipe through which air is supplied to the lower portion of the vat through a header 7 having a series of perforations 8. A closed tank 9 is connected with the pipe 6 and has a. pressure gage 10 and a filling opening and val-vel' l1 through which the purifying agent is deposited in the tank.

12 represents a body of lime, freshly slaked in liquid form, which I prefer to employ as a purifying agent, which is inserted into the tank through the opening l1 and rests upon the bottom thereof, vforming a mass of suitable depth' through which the currents of air must pass before entering the upper portion of the tank. These currents of air are delivered t0 the bottom 'ofl the tank 9 through a pipe 13 which has a blow oft1 14 and is connected to an air pump l5 or ordinary construction. valve 16 regulates the delivery of air to the vat. The currents of air, entering the bottom of the tank, will work up through the lime, bubbling up at the top thereof and throwing the lime upward and keeping it in motion within the tank. The air in the tank pass out of the tank and through the pipe 6 to the bottom of the vat and be discharged into the body of cream or milk therein. I have found this method of aerating the contents of the Vat to be very effective and at the same time the device is an extremely simple and inexpensive adjunct 'to an apparatus for treating cream or milk.

r I have shown the preferred manner of `connecting the,vatwith the receptacle containing the purifying agent, but do not wish to confine myself to this arrangement as the.

connections may be varied and the receptacle for the purifying agent may be modied in various ways Without departing from will thus be thoroughly purified and willl my inventionl I have found, however, that where a purifying agent receptacle of this form is employed, that the lime blown up into the open upper portion of the tank by the pressure of the air current will spread out in a thin spray, and thoroughly wash and cleanse the air in its passage to the outlet at the top of the tank.

I claim as my invention 4 A device of the class described compris` ing a vat adapted to contain cream or. milk, a pipe through which air may be dellvered',

within said vat near the bottom thereof, a closed tank having a pipe connection in its upper walls withl said air pipe and vat and adapted to contain a liquid purifying agent, an air pump having a pipe connection with the lower walls of said tank below the level of said purifying agent, there being a com! paratively large space within said tank above said purifying agent serving as a reservoir for the air accumulating under pressure therein, the air expanding within said tank 'and precipitating impurities which may have passed through said purifying f agent, the pipe leading from said tank to said vat having a valve therein for'regulating the'iow of airunder pressure to said vat.l

In witness whereof,-I have hereunto set myhand thisBlst day of December, 1909.

FRANK E. NooNAN.
